Intended as his final major work for organ, Messiaens Meditations on the Mystery of the Holy Trinity is the culmination of his lifetime work as composer for the organ. Begun as a set of improvisations celebrating the renovation of the organ at Trinité (and the churchs 100th anniversary), Meditations employs new musical languages to explore the mysteries of Christian faith. Born in Avignon to Pierre Messiaen, a Shakespeare scholar, and the poet Cecile Sauvage, Olivier Messiaen (1908-1992) exhibited a rare musical talent from an early age.
